CVE-2022-37922 is a vulnerability identified in Hewlett Packard Enterprise's Aruba EdgeConnect Enterprise Software, specifically affecting versions ECOS 9.2.1.0 and below, ECOS 9.1.3.0 and below, ECOS 9.0.7.0 and below, and ECOS 8.3.7.1 and below. The vulnerability resides in the command line interface (CLI) of the Aruba EdgeConnect Enterprise software, which is used for managing and configuring the network edge devices. This flaw allows remote authenticated users to execute arbitrary commands on the underlying host operating system with root privileges. Essentially, an attacker who has valid credentials to access the CLI can exploit this vulnerability to run any command as the root user, leading to full system compromise. This could include installing malware, altering configurations, exfiltrating sensitive data, or disrupting network services. The vulnerability requires authentication, meaning the attacker must have valid user credentials, but no user interaction beyond authentication is necessary. The exploitability is relatively straightforward once authenticated, given the direct command execution capability. Aruba EdgeConnect Enterprise software is widely deployed in enterprise WAN edge environments to optimize and secure network traffic, making this vulnerability particularly critical in environments relying on this technology for network security and performance. No known exploits have been reported in the wild as of the published date, but the potential impact remains significant due to the level of access granted by the vulnerability. The vulnerability was published on November 30, 2022, and is classified as medium severity by the vendor, though no CVSS score is assigned. The absence of a patch link suggests that users should verify with HPE for available updates or mitigations.

For European organizations, the impact of this vulnerability can be substantial. Aruba EdgeConnect Enterprise software is commonly used in large enterprises, telecommunications providers, and critical infrastructure sectors to manage WAN edge connectivity. A successful exploit could lead to complete control over network edge devices, enabling attackers to intercept, modify, or disrupt network traffic. This could compromise confidentiality by exposing sensitive communications, integrity by altering data flows or configurations, and availability by causing network outages or degraded performance. Given the root-level access, attackers could also pivot to other internal systems, escalating the breach impact. Sectors such as finance, healthcare, manufacturing, and government agencies in Europe that rely on Aruba EdgeConnect for secure and optimized network operations are particularly at risk. The requirement for authentication limits the attack surface to insiders or attackers who have compromised credentials, but this does not eliminate risk since credential theft or phishing attacks are common. The lack of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation. The vulnerability could also be leveraged in targeted attacks against strategic European organizations, potentially impacting national security or critical infrastructure resilience.

European organizations should prioritize the following specific mitigation steps: 1) Immediate inventory and identification of all Aruba EdgeConnect Enterprise devices and software versions in use to determine exposure. 2) Engage with Hewlett Packard Enterprise to obtain and apply the latest patches or firmware updates addressing CVE-2022-37922 as soon as they become available. 3) Restrict CLI access strictly to trusted administrators using strong multi-factor authentication (MFA) to reduce the risk of credential compromise. 4) Implement network segmentation to isolate Aruba EdgeConnect devices from general user networks and limit access to management interfaces to secure management VLANs or VPNs. 5) Monitor logs and network traffic for anomalous CLI activity or unusual command executions indicative of exploitation attempts. 6) Conduct regular credential audits and enforce strong password policies to minimize the risk of unauthorized access. 7) Consider deploying endpoint detection and response (EDR) solutions on management hosts to detect suspicious activities. 8) Educate administrators on phishing and social engineering risks to prevent credential theft. These measures go beyond generic advice by focusing on access control hardening, proactive monitoring, and rapid patch management tailored to the specific nature of this vulnerability.
